"The Debian/Ubuntu battles started almost as soon as it
became clear that Ubuntu was winning the mass popularity that had
always eluded Debian. The war of words had calmed down, but
recently they've caught fire again. This time around the spark,
from what I can see, was when the Debian community "decided to
adopt a new policy of time-based development freezes for future
releases, on a two-year cycle."
"That may not sound like anything to most of you, but many
Debian's developers dislike any but the loosest kind of
organization. This is, after all, a group that includes some people
who refused to work on the distribution because some developers got
paid to work on Debian."
